The 2019 Mercedes-AMG C63 S Coupe mid-life facelift has arrived in Affalterbach’s attempt to keep their most popular performance coupe ahead of the pack, so what’s changed? The main external difference making the facelift instantly recognisable is the ‘Panamericana Grille’ borrowed from the new GT63, combine this with added fins in the front apron, updated headlights, larger exhaust tailpipes plus a new rear diffuser and the C63 S is looking meaner than ever. Mechanically the C63 S has received one major update in the form of a new 9-Speed TRONIC PLUS gearbox lifted straight from the E63 S allowing for increased mid-range acceleration and improved cruising fuel economy in 8th and 9th. In terms of the engine the phrase “you can’t improve on perfection” springs to mind, with class-leading power, huge smooth torque delivery and one of the best exhaust notes of the turbocharged era, it really is no wonder this engine is appearing in more and more cars across the Mercedes range.
